NASA’s Boeing OFT-2: Weather 60% Favorable for Aug. 3 Launch

NASA, Boeing and United Launch Alliance are targeting 1:20 p.m. EDT Tuesday, Aug. 3, for launch of the Orbital Flight Test-2 (OFT-2) to the International Space Station.

For a launch Tuesday, meteorologists with the U.S. Space Force 45th Weather Squadron are predicting a 60% chance of favorable weather. The primary weather concerns for launch day are the cumulus cloud rule, lightning rule and thick cloud rule violations during the instantaneous launch window.
